Table 4.3 showed the data of X3 as the experimental class consited of 17 students. The total of all data which was divided with the number of data determined as mean score from the experimental class was 36.7647. median score was 36.7188.
the median is the numerical value separating the higher half of a data sample, population, or a probability distribution, from the lower half. The mode is defined
10 as the element that appears mose frequently in a given set of elements. The mode score from the table was 37.50. The set of scores constituted a population determined a varience score was 9.191. The highest score of the experimental class was 43.75 and the lowest was 31.25. The sum gained from the total score was 625.00.
According to the table, it could be made a table of frequency distribution which is presented follows :

Table 4.5 showed that the data of X3 as the controlled class was 17 students.
The total of all data which was divided with the number of data determined as mean score from the contrelled class was 41.9112. Median score was 43.7400. The median is the numerical value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. The mode is defined as the element that appears most frequently in a given set of elements. The mode score from the table 37.50. The set of scores constituted a populition determined a variance score was 47.677. The highest score of the controll class was 56.25 and the lowest is 31.25. The sum gained from the total scores was 712.49.

Before the writer calculated the value of t-test to look at the hypothesis, the researcher had to analyze the normality and homogeneity of the data. The examination of normality was needed to know whether the data had been normally distributed. Then, after getting the normality, the next step was calculating the homogeneity of data. It was proposed to look at wheather the data was homogeneous or heterogeneous.
